1. El Arif, Rezki. Design and Implementation of Miniaturized Multi-Band Bandpass Filter with Tunable Transmission Zeros.

Degree: Master, Communications Engineering, 2017, NSYSU

Abstract This thesis presents a stacked stepped impedance resonator (SSIR) structure for designing compact multi-band bandpass filters (BPFs). The multilayer resonator structure is used to reduce the filter size. Moreover, based on the theory of coupled resonators, the desired characteristics of its multiple passbands can be obtained by determining the coupling coefficients and external quality factors. Furthermore, a novel technique has been developed to create controllable transmission zeros (TZs) in the stopbands. This thesis includes four bandpass filter designs with specific requirements. The first BPF design was designed with the center frequency of 3.5 GHz and the FBW of 7.2%. The TZ can be created and adjusted using either magnetic or electric coupling. The overall size of this filter is 4.2 mm 5.2 mm without the feeding lines. The second design proposed a new approach to tune the TZs. By using through vias with the isolation ring slots on the ground plane, the TZs can be controlled effectively. The third design is about the tri-band BPF using stacked stepped impedance resonators (SSIRs). It was designed on a 0.568 mm thick three-layer RT/Duroid 6010 substrate with dielectric constant of 10.2. It occupies an area of 2.8 mm 2.5 mm. The fourth design uses the SSIR structure to design a compact quad-band BPF. The first and third passbands and the second and fourth passbands can be separately adjusted by changing the width of the gaps between two coupled SSIRs in the second and first layer, respectively Advisors/Committee Members: Chih-Wen Kuo (chair), Tzyy-Sheng Horng (committee member), Sholeh Hadi Pramono (committee member), Lih-Tyng Hwang (chair).

2. Mujahidin, Irfan. 5.5-5.8 GHz Directional Antenna with 90 Degree Phase Difference Output.

Degree: Master, Communications Engineering, 2018, NSYSU

The wireless sensor network system requires two antennas that have an output 90 phase difference as a comparison and use a very expensive material for high frequency. 5.5 â 5.8 GHz microstrip antenna frequency equipped with two output 90 degree phase difference in one antenna has been proposed. This thesis presents a 5.5 â 5.8 GHz microstrip antenna with 90-degree phase difference outputs, which is useful in producing directional antennas with circular polarization. The presented antenna consists of a circular patch, a reflector, a pair of feedlines with via holes and a branch-line coupler. The measurement results indicate that the antenna outputs have a phase difference of 86.38 º at 5.5 GHz and 90.98 º at 5.8 GHz. Moreover, the measured gain of the antenna is 3.67 dBi at 5.5 GHz and 5.45 dBi at 5.8 GHz. The overall size of the antenna is 70 mm ï´ 35 mm on an FR4 substrate with dielectric constant of 4.4.

3. Ristika Rahmi Barani, Imee. Orthogonal Hybrid LTE MIMO Antennas for the Smartphone.

Degree: Master, Communications Engineering, 2016, NSYSU

Two orthogonal hybrid antennas for the LTE MIMO operation in the smartphone are presented. The two antennas (one open-slot antenna and one inverted-F antenna) are disposed orthogonally to each other. The open-slot antenna comprises two open slots of different lengths and is disposed parallel and close to the bottom edge of the smartphone. The open-slot antenna operates in the 698~960 MHz and 1710~2690 MHz bands as a main antenna for the LTE/WWAN operation. The inverted-F antenna has a total length of 90 mm and is disposed along one side edge of the device ground plane. The inverted-F antenna can fit in a narrow ground clearance of 1 mm between the display panel and the casing of the smartphone. The side-edge antenna is able to cover the frequency ranges of 824~960 MHz and 1710~2690 MHz for the LTE operation such as in band 5, 8, 10, 25, and 40. Owing to the orthogonal alignment of the two antennas, good envelope correlation coefficients of less than 0.07 are obtained. The ergodic channel capacity is calculated to reach about 9.3~10.7 bps/Hz at 20-dB signal-to-noise ratio. Details of the MIMO antenna structure and its operating principle are described. Experimental results of the fabricated prototype are presented and discussed. Effects of the display panel and userâs hand on the MIMO performance are also analyzed.
